15 First Grade STEM Projects Kids Actually Love (Easy, Low-Prep Ideas)
First graders are natural scientists. They ask big questions, test ideas quickly, and love to build with their hands.
The hard part for teachers is finding STEM projects that are simple to prep, classroom-friendly, and genuinely exciting for 6- and 7-year-olds.
This list gives you exactly that.
When students can see, build, and explain their ideas, STEM becomes more meaningful and memorable.
What makes a great first grade STEM project?
Strong STEM projects for this age are:
- Short enough for attention spans (20 to 45 minutes)
- Hands-on and visual
- Built around one clear question
- Open-ended enough for creativity
- Easy to discuss with sentence stems like “I noticed…” and “I changed…“
15 first grade STEM project ideas
1) Animal Adaptation Design Challenge (with Drawings Alive)
Students choose a habitat (desert, arctic, forest, or ocean), draw an animal with survival features, and explain how those features help it live there.
Then use Drawings Alive to turn that student drawing into something they can proudly share with classmates and families.
The biggest benefit is not the tool itself. It is student ownership: kids feel seen, motivated, and eager to explain their science thinking when their own drawing becomes the centerpiece.
Why teachers love it: one activity combines life science, engineering thinking, art, and speaking.
2) Build a Bridge for Toy Animals
Using straws, craft sticks, or paper tubes, students design a bridge that can hold plastic animals.
3) Weather-Proof Shelter
Can students build a tiny shelter that keeps a tissue dry during a spray-bottle rain test?
4) Sink or Float Lab
Students predict, test, and sort classroom objects.
5) Paper Airplane Engineers
Students design a paper airplane for distance, test, and improve.
6) Plant Growth Experiment
Grow seeds with different light or water conditions and track results.
7) Marble Maze Build
Students create a cardboard maze and test how quickly a marble reaches the finish.
8) Tallest Tower Challenge
Using cups and index cards, teams build the tallest free-standing structure.
9) Sound and Vibration Station
Build simple instruments and explore how vibrations create sound.
10) Magnetic Mystery Hunt
Students test classroom objects and sort magnetic vs. non-magnetic.
11) Shadow Tracking Investigation
Trace outdoor shadows during the day and compare direction and length.
12) Ramp and Roll Test
Build ramps at different heights and measure how far objects roll.
13) Recycled Boat Challenge
Design a mini boat from recycled materials and test how many pennies it can hold.
14) Unplugged Coding Maze
Students write step-by-step directions to guide a classmate through a taped floor maze.
15) Pollinator Flower Design
Students design a model flower to attract bees or butterflies and explain why it works.
Why Drawings Alive is a great STEM add-on for first grade
Many STEM activities end as soon as students finish building.
Drawings Alive extends learning by making student ideas visible and easier to explain. It works especially well in:
- Animal adaptation projects
- Habitat units (desert, arctic, forest, ocean)
- Science storytelling (students explain their animal in a short story)
- Speaking and writing practice (quick presentations plus 3-5 sentence responses)
Drawings Alive can also generate short videos and 3D models, which can be used as optional showcase pieces for project sharing days.
When students can see their idea come alive, they usually give stronger explanations and use more specific vocabulary.
Quick teacher tips to keep STEM low-prep
- Pre-sort materials into table bins
- Use one routine each week: Ask -> Plan -> Build -> Test -> Improve -> Share
- Give one success criterion at a time
- End with a 2-minute reflection
If you only try one activity from this list, start with the adaptation challenge. It is high-engagement, standards-friendly, and easy to connect with reading and writing.
